Yep, mine went from 53 miles in mid-seventies temperatures to 43 miles in mid-thirties temperatures.
Yup but with the TDI you're getting your heat as waste from all that fuel.While I had a milage decrease with my tdi in cold weather it was 10% or less range difference in a full tank which was 570 miles in really cold weather to 630 in warm weather.
The difference is I didn't have to do that. Yes ic engines are inherently inefficient and produce almost equal heat to useful energy, but in the winter it's free heat. So yes it has less lost range vs the volt in winter since I am not going to suffer to get a few more miles since it isn't going to go the whole trip on ev anyway.Yup but with the TDI you're getting your heat as waste from all that fuel.
I'll bet it would be closer to 10% at 50F if you only counted traction energy.
Put on your winter gear, do some test runs and let us know ;-)
Not to start a debate but from everything I've read it's more like 3:1 even for a very efficient engine.Yes ic engines are inherently inefficient and produce almost equal heat to useful energy, but in the winter it's free heat.
It does sound like a Bolt would've been a better fit for your needs. No matter you should still be able to get better mileage in the Volt than the tdi and you can do your city/shopping drives in EV.I am curious to see how much range I loose when it gets warm and I run the ac. In the tdi I ran heat or ac, almost never vent only.
... Turns out my shortest days are 50 miles and most are closer to 80, not even an issue in a tdi with a 600 mile range.
That was once true, but it's a bit pessimistic in the era of direct injection, EGR, and miller cycle engines. If by "very efficient engine" you mean the current automotive record holder, the gen IV prius, than the actual ratio is 1.5:1.Not to start a debate but from everything I've read it's more like 3:1 even for a very efficient engine.
